[Music] do [Music] welcome back i'm laura lepink and in this video we are going to go over how to glaze your windows so the first step that you want to do is work on cleaning your glass we want to make sure that we have good adhesion between the glazing putty and the glass and if our components are dirty then it can affect how these pieces of glass will fit back into their spot in the window we do have a couple of pieces of glass that have been pre-prepared and the first thing that we need to do is treat the rabbit and the rabbit is this little l-shaped ledge that the glass will sit into and what i mean by that is that we want to treat it with something to make sure that it's not really dry if we have very dry wood then it could cause our glazing putty to dry prematurely and crack and it may not last as long the product that i'm going to use today is a product called flood penetral and so i'm going in with just a little disposable chip brush and i'm just going to kind of do a light application around the edge you're looking for the product to be soaking into the wood and so the wood will sometimes look a little bit darker in color as it starts to become a little bit more hydrated so now that we've let the penetrol sit for a few minutes here we're just going to kind of dab away any of that extra penetrol that wasn't able to soak into the wood and then our glazing rabbit should be ready to glaze there are other types of glazing putty today because of its more rapid paintability we are using a type called glazol with linseed oil based putties like sarcoglase you can rehydrate them by adding a little bit of linseed oil if it's too sticky you can add something called whiting powder which is basically basically calcium carbonate you can find it at ceramic shops or even some paint chops so the first thing we're going to do is bed the glass we want to make sure underneath on this rabbit that the glass will be sitting on glazing putty you can't really overfill this ledge because when you press it down the extra glazing putty will end up kind of pushing out either on the front side or the back side and we can remove that and reuse that glazing once you've put glazing all around this rabbit edge we'll then move on to bedding the glass and so i'm going to take my well-marked piece of glass here and i'm going to drop it in so it's just sitting on top what do you want to see along the edge is that on the rabbit edge it's fully filled with that glazing putty but once that's completed and we can see there aren't any gaps we will move on to putting the glazing points in which are little pieces of metal that we are going to shoot into the sides of these wood pieces so like the rail and the mutton to hold it in place basically they have a point but they also have this lip and what that lip will allow you to do is to even be able to press in this glazing point with a putty knife so you can put your putty knife against and you can press it into the side and so the type that i use most frequently are the diamond point glazing points i'm going to hold this against the wood flat and i'm just going to pull and what it'll do is it's pushed that small glazing point into the side of the wood that is now holding the painted glass in place and repeat on this side and we're going to shoot it in and see if we can get those to slot correctly so now that we have the glazing points in what we're actually going to do is flip your window over and what i'm going to do is cut away this extra glazing putty on this back side and all this putty is still good as long as it doesn't have like a lot of debris or anything in it it should be able to be used again and so i just put it back into with the rest you may have to come back in here and clean it up again a little later because as we press down when we glaze the window a little bit more putty can kind of squish out that should be good and giving us a clear picture of where we need to glaze because we're going to fill these edges with glazing and then we're going to cut it back with either this glazing tool or an angled putty knife and so again what i end up doing is just taking kind of a chunk of this glazing putty and i'm going to put a little on my glazing knife i'm going to kind of just fill in this gap so how i shape putty is i usually go in one long line and kind of one pull i like to hold my wrist in the same position so first i will cut in to the corner at the ankle that i want the corner at then i tilt it down and i'm going to let this wood edge guide my putty knife so i'm pressing down i'm dragging it towards me i'm keeping my wrist kind of locked in place and i'm going to tilt it up and kind of come into that corner after this you can kind of pull the putty away from this side very gently but once you have that part out all you have to do is you kind of roll the extra putty you cut off out of the way i want my glazing putty to be about the width of the rabbet so when i look at this it's a little bit thick so i'm going to come in here come in at this angle again i'm going to cut a little bit more off and kind of continue pressing in at that point what you end up doing is working your way around the window so i like to shift my window because i am right hand dominant because then i'm gonna come at this corner that i just worked on and i'm gonna cut into the corner at the angle i want that corner and pull and cut into that other one to finish up this process you pull and shape all four of these sides at the end which is kind of a clean up and setting point for the putty what you want to do is use your whiting powder which is the calcium carbonate you basically just come in and dust along this edge and what this does especially with linseed oil based putties like sarco glaze is create like a little bit more of a skin which kind of protects the putty a little bit more and that is pretty much the glazing process you let that sit and make sure the glazing putty is hardened a little bit before you end up painting [Music]
